Switching from factory zenon to led headlights

I accidentally purchased some LED headlights and am wondering if I could bypass the ballast and use the LED headlights????

I think you could but the stock headlight housing probably won't project the correct light pattern and might be a safety hazzard for oncoming drivers.
Try some of the lightbulb forums (yes, even they have their own forums) and see what you can find out about bulb conversions and light patterns.

Ask the vendor if the LED bulbs are designed for halogen or HID. I suspect the former. The HID reflectors and lenses are designed for HID bulbs, so Santaclause4 is probably correct.

I actually purchased the whole headlight assembly not just the bulb. I emailed the vendor and they couldn't comment on it they said. I went back to look at the item and the vendor changed the description (does not work with Zenón models). This wasn't there before.
